i have an exception caught with this code and i can't pinpoint the error.
def paypal_content
payment = {}
payment[:intent] = "sale"
payment[:payer] = { :payment_method => "paypal" }
payment[:redirect_urls] = { :return_url => "http://localhost:3000/payment/execute", :cancel_url => "http://localhost:3000"}
items = []
index = 0
@cart.items.each do |item|
items[index] = {}
items[index][:name] = item.title
items[index][:sku] = item.artist
items[index][:price] = item.price.to_s
items[index][:quantity] = "1"
items[index][:currency] = "CHF"
index++
end <--- this is line 109
item_list = {}
item_list[:items] = items
transactions = []
transactions[0] = {}
transactions[0][:item_list] = item_list
transactions[0][:amount] = { :total => @cart.total_price.to_s, :currency => "CHF"}
transactions[0][:description] = "from Larraby Blaine Esquire"
payment[:transactions] = transactions
return payment
end
the error is home_controller.rb:109 syntax error, unexpected keyword_end home_controller.rb:125: syntax error, unexpected $end, expecting keyword_end
If i remove the each block everithing is fine, so i guess i made a mistake with the block but what mistake ??????
Ruby does not know ++
, write += 1
.
When you write index++
, it thinks the first +
is addition, and the second +
a unary sign. You can't have a sign without something after it, so it expects an expression, but finds end
